Description
THZ2, an analogue of THZ1 with improved pharmacokinetic features, is a potent, selective CDK7 inhibitor with IC50 of 13.9nM, displays a 5-fold improved half-life in vivo compared with THZ1; selectively targets CDK7 and potently inhibits the growth of triple-negative but not ER/PR+ breast cancer cells, efficiently suppresses the clonogenic growth of TNBC cells with IC50 of 10nM; Like THZ1, THZ2 induces apoptotic cell death in triple-negative but not ER/PR+ breast cancer cells or normal human cells; suppresses the growth of triple-negative breast tumors in xenograft models
